Givens is ranked 28th in DPAR and 34th in DVOA.
When I look at the numbers, I do not see that "they really are pretty average for a #2 WR" instead I see numbers that put Givens in the top echelon of #2 wide receivers and numbers that are better than several #1 wideouts.
BTW, Givens ran a faster 40 in the NFL combines (4.56) than did Darrell Jackson (4.58). So, there is no empirical evidence that Jackson is closer to a speed burner than is Givens.
